Transcript of MCPET

Die Cutting
Die cutting is ideal for mass production with high end tooling achieving tight tolerances and for simple shapes with low tolerances.
Lead times can vary from a few days to several weeks depending upon level of precision required and number of impressions in each tool.
Costs will again also be impacted significantly depending upon the complexity and tolerance levels.
These aspects may also differ between processor and tool maker.
Laser Cutting
In the case of laser cutting a CAD file is put in to the system computer and cutting can be initiated without the need for any investment for tooling. Further more should an adjustment be required due to a design change it is a very simple process without any additional investment.
As we can see here in this example of laser cutting, it is possible to reduce waste to an absolute minimum due to the fact that only very small gaps between components are required.
This ensures that you can achieve highly cost efficient production with regards to material maximization.
One of the major physical merits of MCPET is that it does not require heavy machining or aluminium backing to support it in a fixture after simple creasing. Here we can see that after the laser has made a cut into but not through the material it can be bent in to specific angles by hand or very simple machinery.
Automated blade cutting
There are various technologies available to processors but here we can see a system that enables the operator to input a CAD file and the machine will calculate the optimum layout. Then depending upon the cutting needs its multi function head will select blades or punches to achieve the parts required.
Many of our processors have the capability and 3rd party materials available to provide further value adding features such as adhesive and aluminium backing as required.
In order to prevent light transmission through the walls of the product it is important to ensure a minimum thickness of 0.4 mm after forming.
As RB grade starts with 0.94 mm and POLYCA 1.00 mm this ensures a good starting thickness to work with.
MCPET-RBgrade & MCPOLYCA are ideal for thermoforming
